The irrigational method for cyst cavity was performed on a case of a large follicular dental cyst which developed in the ramus of the mandible. It had been shown that the inflammatory symptoms were relieved rapidly with this therapy and that the impacted tooth erupted gradually with the cyst cavity decreased in size. About seven months following the beginning of this treatment, the cyst cavity was reduced to the size of the tip of an index on the X-ray film and the volutne of cyst fluid decreased to no more than 1 ml. About one year later, the cyst was completely ennucleated by the Partsch II method, but the epithelium lining of the cyst wall was not observed on the histological examination.<BR>In order to define the course of bone regeneration, the density of radiolucent region in the orthopantomogram X-ray films was measured by an apparatus of SAKURA microdensitometer. As et result, it was suggested that the bone regeneration advanced at an early stage owing to this treatment.<BR>Finally the irrigational method was compared with the marsupialization in the existing literature, and it was considered that this method was quite useful for the pre-operative treatment of large cysts in jaws.
